HP FET MULTIPLEXER E1351A/53A guide

SETTling[:TIME] [ROUTe:]SETTling[:TIME] <channel_list> sets the delay between receipt of a channel closing trigger, and the pulse when the FET channel is closed. You must specify one and only one channel for each card in the instrument which has a channel in the channel list, and the <time> will then apply to all channels on the card. The range is 1 to 32768 μsec.

Parameters

Parameter Name	Parameter Type	Range of Values

time	Numeric	1E-6 32768E-6 MIN MAX

channel_list	Numeric	only one channel

Comments ∙ Digital Bus Handshaking: This command allows a user-defined settling time to allow a measurement to be made before the next channel is closed.

∙Related Commands: TRIGger:SOURce DBUS, TRIGger:SOURce IMMediate

Example Setting 16 μsec SETTling TIME

TRIGger:SOUR DBUS	Triggering on the digital bus
	handshake lines
SETTling:TIME 16E-6	Delay = l6μsec

SETTling[:TIME]? [ROUTe:]SETTling[:TIME]? [MIN MAX] <channel_list> returns the

current setting for a specified channel. MIN or MAX returns the minimum and maximum allowable settings.

Parameters

Parameter Name	Parameter Type	Range of Values

MIN MAX	Numeric	MIN = 1 μsec, MAX = 32768 μsec

channel_list	Numeric	only one channel

Comments ∙ Returned value is given in exponential notation.

Example Set and Query the SETTling TIME

SETT:TIME 16E-6	Sets delay = 16μsec.
SETT:TIME?	Returns + 1.600000E-005.
